Silicon Valley-based semiconductor startup SiFive has raised $400 million in a Series G funding round, marking a significant milestone in its expansion into data center chip technology. The round was led by Atreides Management and included major investors such as Nvidia, Apollo Global Management, Point72, and T. Rowe Price Investment Management. The funding values the company at $3.65 billion and reflects growing investor confidence in next-generation chip architectures.
The company plans to use the $400 million investment to accelerate the development of its data center-focused central processing units, targeting the rapidly expanding market driven by artificial intelligence and high-performance computing demands. SiFive’s approach centers on building customizable processor designs that can be tailored by clients for specific workloads, offering greater flexibility compared to traditional chip manufacturing models.
Unlike conventional semiconductor firms, SiFive operates on a licensing model, providing chip blueprints rather than manufacturing chips directly. Its designs are based on the open-standard RISC-V architecture, which is gaining traction as an alternative to proprietary systems such as Arm. This open approach allows companies to develop customized chips while avoiding dependence on a single vendor, a factor increasingly valued in the evolving semiconductor landscape.
The funding comes at a time when competition in the data center chip market is intensifying, with players such as Nvidia, Arm, and Intel expanding their offerings to meet rising demand. SiFive sees this as an opportunity to position itself as a key provider of flexible and scalable CPU solutions, particularly as enterprises seek optimized hardware for AI-driven workloads and large-scale data processing.
SiFive CEO Patrick Little indicated that this could be the company’s final funding round before pursuing a public offering, although no timeline has been disclosed. As demand for AI infrastructure continues to surge, the company aims to leverage its expertise in RISC-V technology to capture a larger share of the data center market and strengthen its role in the global semiconductor ecosystem.
